GGAS: Ground Guiding Assistant System for Interactive Indoor Wayfinding

This paper introduces an innovative wayfinding system featuring addressable LED strips mounted on the ground of an environment, controlled via conventional button interfaces and advanced voice interaction integrated with GPT-4. These LED strips provide visual cues to guide users to various rooms, enhancing navigation. We detail the hardware setup, including LEDs, controllers, and network infrastructure, along with the design of the user interfaces. The system’s performance was evaluated through a user survey, which indicated a preference for the touch interface while also highlighting the potential of voice interaction. Our findings demonstrate the system’s effectiveness in providing intuitive and flexible navigation assistance without requiring additional user hardware. The proposed approach, the Ground Guiding Assistant System (GGAS), is implemented and utilized daily in an $813 \mathrm{~m}^{2}$ office addressing 13 rooms at the Center for Tangible AI (ZEKI) in Berlin.
